Abstract
We analyze the atmospheric neutrino experiments of SuperKamiokande including zenith angle dependences using the three-flavor neutrino framework with the hierarchy m12 ≈ m22 < m32. Taking into account the terrestrial, solar neutrino experimental data and the atmospheric neutrino experiments, including the sub-GeV and multi-GeV data in SuperKamiokande, a large angle solution in the solar neutrino experiments is favored and the range of the mass parameter Δm232 is restricted in the range 0.08eV2−2eV2. Allowed regions of mixing parameters are θ13 < 4°, 27° < θ23 < 32° for Δ m232 = 1 eV2 and θ13 < 3°, 28° < θ23 < 33° for Δm232 = 0.1 eV2.
